2. Description of Related Art Including Information Disclosed Under 37 CFR 1.97 and 1.98

Personal watercraft floats are well known. Common features of a dry dock watercraft float consist of a durable plastic shell outside and air or foam filled inside. The watercraft is driven onto the float with guidance of the floats rails, which are generally located on top of the float. Often, there is a high cost associated with the storage and transportation of watercraft floats due to their bulk. To compensate for this problem several prior art devices are a simple float device with a hull receiving channel. These devices do not have the added safety of a bow stop device. The bow stop is needed to safely stop the forward movement of a watercraft being driven up onto the float and for mooring the float. What is needed is a removably attachable bow stop with a mooring loop for a stackable personal watercraft floatation device, which will help retail customers and wholesalers who buy and store the stackable watercraft products benefit from a reduction in cost of shipping and storage of these items.

Prior art devices do not provide a removable bow stop device for a personal watercraft floatation device which can be removed from a bow stop recess at the front of a float and placed in one of the four recessed in the corners of the float for stacking the floats for transportation and storage of the stacked floats.

U.S. Pat. No. 6,006,687, issued Dec. 28, 1999 to Hillman, provides a modular floating boat lift capable of accommodating a wide variety of V-hulled boats. The boat lift is comprised of docking members, a bow stop that protects the hull of the boat, a stern segment and at least one intermediate segment. The stern segment and intermediate segment contain a channel with rollers that assist in conveying the boat over the boat lift and supporting the boat when docked. The rollers have different height configurations and can be positioned in different trays in the channel so that they can be used with boats that have different dead rise angles.

U.S. Pat. No. 5,855,180, issued Jan. 5, 1999 to Masters, puts forth a tilting dry dock upon which a small watercraft may be docked in a dry condition and from which a boater may access from an associated structure for launching the watercraft without entering the water. The dry dock comprises a floating dock having a forward end and a rear entry end. A motion mechanism connects the floating dock to the pier. The motion mechanism includes a mechanical pivot carried by the floating dock by which the floating dock is connected to the associated structure. The floating dock pivots about the pivot during docking and launching of the watercraft in a seesaw motion. A buoyant fulcrum is included in the floating dock which provides buoyancy and assists the seesaw motion of the floating dock during docking of the watercraft. The dry dock seesaws between an entry position in which the floating dock is tilted rearwardly for receiving a bow section of the watercraft to initiate docking and a docked position in which the watercraft is moved forward on the floating dock and the floating dock tilted forwardly from the entry position. The motion mechanism includes a connecting link pivotally connecting the floating dock and the pier which moves in a vertical motion. A limit element limits the range of the vertical motion of the connecting link as the floating dock seesaws.

No. 6,431,106 issued Aug. 13, 2002; No. 5,947,050 issued Sep. 7, 1999; No. 5,931,113 issued Aug. 3, 1999; No. 5,682,833 issued Nov. 4, 1997 and No. 5,529,013 issued Jun. 25, 1996 to Eva, III, disclose a floating, drive-on dry dock assembly for a small craft which is assembled from two kinds of hollow floatation units, tall units and short units. The units are interconnected so that their top surfaces are substantially coplanar. The units are arranged to form two arms which support the hull of the craft on each side of the longitudinal center line of the craft. The entire length of each arm is made up of tall units except the distal end portions of each arm which may be made up of short units. The short units are able to flex downward as a craft begins to ride up on the dock because of the location of the connection between adjacent units. The tall units, however, cannot flex relative to each other nearly to the same extent as the short units, and so they form a stable generally planar surface. The distal ends of the arms are connected to each other by an upside down short unit. The short units are proportioned so that the uppermost surface of each is out of the water both when the dock is empty and when a craft is “parked” on the dock.

Two U.S. Pat. No. 5,941,660 issued Aug. 24, 1999 and No. 5,795,098 issued Aug. 18, 1998 to Rueckert, indicate a modular watercraft support structure formed from a plurality of rigid platforms that are coupled together by the use of linking pins or insertion plugs. Each platform having independent buoyancy formed integral therein for support of most any size watercraft. The structure includes multiple ramp, cradle, and flat platforms, allowing an individual to customize a support structure for a particular sized watercraft. The platforms allow the structure to raise or fall with each tidal change. One embodiment of the dock assembly includes a hinge-type connection that promotes ease of loading and unloading of a watercraft. The dock assembly may also be configured to provide a surface to which watercraft may be moored.

What is needed is a removable bow stop device for a personal watercraft floatation device which can be removed from a bow stop recess at the front of a float and placed in one of the four recessed in the corners of the float for stacking the floats for transportation and storage of the stacked floats.

BRIEF SUMMARY OF THE INVENTION

An object of the present invention is to provide a removable bow stop device for a personal watercraft floatation device which can be removed from a bow stop recess at the front of a float and placed in one of the four recessed in the corners of the float for stacking the floats for transportation and storage of the stacked floats.

Another object of the present invention is to provide a removable bow stop device which has a built-in loop for tying a mooring line to secure a personal watercraft to the float.

In brief, a removably attachable bow stop for a stackable watercraft float system has a molded mooring loop which allows a watercraft to tie onto it so that the watercraft will be secured on the float. The bow stop has two vertical side notches with bottom screw holes to screw the bow stop removably within a mating shaped bow stop recess near the front end of the float adjacent to the forward end of the mounting ramp for the personal watercraft on the top surface of the float. Each watercraft float has a pair of spaced parallel indented slots on a bottom of the float to receive and mate with two protruding spaced parallel tracks on the top of each float so that a number of the floats can be stacked together for transportation and storage in a stack which takes up less vertical space than floats with no bottom slots to receive the top tracks. Four recessed corners of the stackable float have openings to receive a PVC pipe for securing the floating dock to a stationary dock or into the sand below the water. The removably attachable bow stop can be placed in one of the recessed corners of the stackable float for compact storage or shipment.

An advantage of the present invention is that it provides a resilient rubberized plastic bow stop means for stopping the forward motion of a personal watercraft onto the stackable float for mooring the watercraft without damaging the portable watercraft.

Another advantage of the present invention is that the bow stop has a mooring loop to tie the personal watercraft to the float.

A further advantage of the present invention is that the bow stop is removable to fit into a recessed corner of the stackable float for stacking a number of floats in a closely stacked array for shipping and storage to save space and costs of shipping and storage.

In FIGS. 1-7, an attachable removable bow stop 20 for a watercraft float 40 comprises a main body portion 21 having an angled recess 22 extending from a top surface 26 to a back surface 27 of the main body for receiving a portion of a bow 51 of a watercraft 50 (shown dashed) therein, as shown in FIG. 5.

The bow stop 20 is formed of a molded synthetic material having a shock absorbing quality serving as a means to absorb the shock of the portion of the bow 51 of the watercraft in the angled recess 22 without damage to the watercraft 50. In FIGS. 2 and 3, a molded mooring loop 25 is formed on a front surface 29 of the main body 21 for receiving a line from a watercraft to secure the watercraft to the mooring loop.

In FIG. 2, a flat substantially rectangular bottom surface 28 of the bow stop 20 mates with a bow stop receiving recess 46 in a top of a stackable watercraft float 40 for removably receiving the bow stop 20 therein, as shown in FIG. 5, to fit with a tight friction fit at a front portion of an angled ramp surface 42 of the stackable watercraft float 40 for receiving a watercraft 50 moving onto the angled ramp surface 42.

A means for removably attaching the bow stop 20 to the stackable watercraft float in the bow stop receiving recess 46 to secure the bow stop therein so that the bow stop stops forward movement of a watercraft 50 moving onto the stackable watercraft float comprises at least one opening 24 in the bow stop for receiving a removable connector connecting to the stackable watercraft float 20. Preferably the main body 21 has a pair of recesses 23 in two sides 30 of the main body with a bottom surface of each of the recesses having an opening 24 therethrough to receive a threaded connector for removable attachment of the bow stop to the stackable watercraft float 40.

In FIGS. 6 and 7, the bow stop 20 is configured to fit alternately within a corner recess 45, 45A and 45B of the stackable watercraft float 40 so that the bow stop 20, 20A and 20B is positioned below a top surface of the stackable watercraft float so that a number of watercraft floats are stackable in a close stacked vertical array with the top surface of a lower stackable watercraft float contacting a bottom surface of an upper stackable watercraft float in the close stacked vertical array, as in FIG. 7.

In FIG. 7, each stackable watercraft float 40, as claimed in applicant's U.S. Pat. No. 7,063,033, has a pair of spaced parallel indented slots 43 on a bottom of the float to receive and mate with two protruding spaced parallel tracks 41 on the top of each float so that a number of the floats can be stacked together for transportation and storage in a stack which takes up less vertical space than floats with no bottom slots to receive the top tracks. The closely stacked array for shipping and storage to save space and costs in shipping and storage.

In use, the bow stop 20 screws onto the stackable watercraft float 40 in the bow stop receiving recess 46 at the desired position of the bow 51 of a watercraft resting on the float for mooring, so that the forward movement of the watercraft 50 on the float is stopped by the bow stop 20 to position the watercraft in the right place for mooring. The watercraft 50 is tied to the loop 25 on the front of the bow stop for mooring.
